generic

Workarounds

  1. 88% success Optimize Lua script to be faster or break into smaller operations
  2. 82% success Use SCRIPT KILL if no writes, or SHUTDOWN NOSAVE as last resort

Dead Ends

  1. Use SCRIPT KILL without checking if script has writes 78% fail

    If script did writes, KILL fails

  2. Set lua-time-limit to 0 85% fail
